There are several isotopes of francium. Starting with 87220Fr, and going on up to 87232Fr, beta- decay is present in one form or another. Below 87220Fr, we start to see beta+ decay. Mixed in with all of this, we see alpha decay from time to time.
Beta-
A neutron is converted into a proton, increasing the atomic number by 1, and keeping the Atomic Mass number the same. If the parent were 87222Fr, for example, the daughter would be 88222Ra. (Radium) Resulting emissions would include beta particles in the form of electrons and electron antineutrinos, as well as gamma and x-ray from time to time.
Beta+
A proton is converted into a neutron, decreasing the atomic number by 1, and keeping the atomic mass number the same. If the parent were 87212Fr, for example, the daughter would be 86212Rn. (Radon). Resulting emissions would include beta particles in the form of positrons and electron neutrinos, as well as gamma and x-ray from time to time.
Alpha
A helium nucleus, 24He2+, is ejected, reducing the atomic number by 2, and reducing the atomic mass number by 4. If the parent were 87212Fr, for example, the daughter would be 85208At. (Astatine) Resulting emissions would be the helium nucleus as described above, as well as gamma and x-ray from time to time.
Note that I chose 87212Fr deliberately, because it does have two decay sequences, both alpha, and beta+.

What element decays to form helium and francium?
Uranium-235 decays to form helium and francium through a series of alpha and beta decay reactions. Helium is typically produced as an alpha particle, while francium is formed as the end product of the decay chain.
What letter balance the beta decay equation 223 87?
In beta decay, a neutron in the nucleus transforms into a proton while emitting a beta particle (an electron) and an antineutrino. For the isotope 223/87 Fr (Francium), the beta decay equation can be represented as: [ ^{223}{87}Fr \rightarrow ^{223}{88}Ra + \beta^- + \bar{\nu} ] Here, Fr (Francium) decays into Ra (Radium) with the atomic number increasing by one, and a beta particle (β-) is emitted.
What is the name of the product nuclide when bismuth-214 undergoes beta decay?
Bismuth-214 produces Polonium-214 by beta- decay. It also produces Thallium-210 by alpha decay, though at a much smaller percentage.
What is the other product in a beta decay of zirconium-93?
The other product in the beta decay of zirconium-93 is niobium-93. In beta decay, a neutron in the nucleus is converted to a proton, resulting in the formation of a new element with one higher atomic number.
What is the product of nitogen-17 beta decay?
The product of nitrogen-17 beta decay is oxygen-17. During beta decay, a neutron in the nitrogen-17 nucleus is converted into a proton, resulting in the emission of a beta particle (an electron) and an electron antineutrino.
What would be the product of the beta decay of bismuth?
The product of beta decay of bismuth-209 is thallium-209. During beta decay, a neutron in the bismuth nucleus is converted into a proton, resulting in the emission of a beta particle (electron) and an antineutrino.
What is the product of the beta decay of bismuth?
The product of the beta decay of bismuth-214 is the stable element polonium-214. During beta decay, a neutron in the nucleus of bismuth-214 is converted into a proton, with the emission of an electron (beta particle) and an antineutrino.

Who made francium?
Natural francium is the decay product of actinium-227. Francium can be also obtained by nuclear reactions.

What is the daughter product in the beta decay of 144Ce?
The daughter product in the beta decay of 144Ce is 144Pr, which stands for promethium. Promethium is a radioactive element that forms as a result of the beta decay of cerium-144.
What is francium's most abundant isotope?
Francium has no stable isotopes. That means it doesn't really have a "most abundant" isotope; they're all pretty much nonexistent. There are trace amounts of 223Fr in uranium minerals, because it's a decay product of 227Ac (which is itself a decay product in the decay chain of uranium).
What is the product of radioactive decay symbolized by called?

What is the product of beta decay potassium-42?
The product of beta decay of potassium-42 is calcium-42. In beta decay, a neutron in the potassium-42 nucleus is converted into a proton and an electron (beta particle), leading to the formation of calcium-42.

What is the nuclear decay for francium?
Francium-223 decay to radium-223; each isotope have another type of decay.
